Using EWS differences beetwen with Exchange 2010 server and Exchange 2007 server?

If you talk to exchange 2010 with 2007's wsdl - no differences at all.

If you talk to exchange 2010 with 2007's wsdl - no differences at all. If you talk to exchange 2007 with 2010's wsdl it works pretty fine as well, however you should be careful not to use 2010 specific methods/properties. EWS 2010 introduces new functionality like associated items you can't use from 2007.

Also of note is that the feature set for EWS is different between Exchange 2007 and Exchange 2007 sp1 – Mark Hosang May 25 at 2:30 True, however you can point out in the product's requirements that SP1 is required. Updating to SP1 isn't complicated at all, and most probably admins will alredy have it installed if they care about security. This is not like updating from 2003 to 2010.

Our service for example will simply shutdown if non SP1 of 2007 detected. – aloneguid May 25 at 21:34 I mentioned it just as a potential pitfall, since the EWS feature is different. As one of my clients JUST upgraded to SP1 2007 SP1 this year.

Though I do agree with you in that it isn't as major an upgrade. – Mark Hosang May 26 at 1:10.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
